Religion is an organized collection of belief systems, cultural systems, and world views that relate humanity to spirituality and, sometimes, to moral values. Many religions have narratives, symbols, traditions and sacred histories that are intended to give meaning to life or to explain the origin of life or the Universe. From their ideas about the cosmos and human nature, they tend to derive morality, ethics, religious laws or a preferred lifestyle. According to some estimates, there are roughly 4,200 religions in the world. [Wikipedia]
